Kerr-Schild ansatz in Einstein-Gauss-Bonnet gravity: An exact vacuum solution in five dimensions
Andres Anabalon, Nathalie Deruelle, Yoshiyuki Morisawa +4
As is well-known, Kerr-Schild metrics linearize the Einstein tensor. We shall see here that they also simplify the Gauss-Bonnet tensor, which turns out to be only quadratic in the…
Some considerations on the Mac Dowell-Mansouri action
Andres Anabalon
A precise relation is established between the Stelle-West formulation of the Mac Dowell-Mansouri approach to a gauge theory of gravity and the approach based on a gauged Wess-Zumin…
The Universe as a topological defect
Andres Anabalon, Steven Willison, Jorge Zanelli
Four-dimensional Einstein's General Relativity is shown to arise from a gauge theory for the conformal group, SO(4,2). The theory is constructed from a topological dimensional redu…
General Relativity from a gauged WZW term
Andres Anabalon, Steven Willison, Jorge Zanelli
In this paper two things are done. First it is shown how a four dimensional gauged Wess-Zumino-Witten term arises from the five dimensional Einstein-Hilbert plus Gauss-Bonnet lagra…
N=4 superconformal mechanics as a Non linear Realization
Andres Anabalon, Joaquim Gomis, Kiyoshi Kamimura +1
An action for a superconformal particle is constructed using the non linear realization method for the group PSU(1,1|2), without introducing superfields. The connection between PSU…
